Given numbers are 990,598,145,242,770

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 990,598,145,242,770 is 660990330.

Find LCM of 990,598,145,242,770 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 11 x 9 x 299 x 29 x 11 x 7 = 660990330

Therefore, the lowest common multiple of 990,598,145,242,770 is 660990330.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

990 x 598 x 145 x 242 x 770 = 15995965986000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

598 : 1, 2, 13, 23, 26, 46, 299, 598

145 : 1, 5, 29, 145

242 : 1, 2, 11, 22, 121, 242

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,598,145,242,770, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

598:2x 13x 23

145:5x 29

242:2x 11x 11

770:2x 5x 7x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 5x 5x 11x 11 = 24200

Therefore, the value for common factors is 24200.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 15995965986000/(1x24200)

LCM = 15995965986000/24200

LCM = 660990330

Thus, we can understand that the LCM of 990,598,145,242,770 is 660990330.
